Original application filed October To all whom it may concern Y Be it known'that I, AnNo A. Ewan). a citizen of the United States, residing at Oakfield, in the county of Fond du Lee and State of isconsin, have invented certain new and useful Improvements in Tire-Inflating Devices; and I do declare the following to be a full, clear,.and exact description 01 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This application relates to tire inflating devices and is divisional from my pending U. S. application, Serial No. 418,497. Inflation'devices or the class involve-d herein are each provided with a vertically movable hose-carrying arm pivoted to a standard whose upper end carriesa globe for displayingthe words Free air, advertisements, etc. Means are provided for raising the arm after each use of the hose and the aim of the present invention is to provide a novel as sociation of parts obscured in the globe and standard for cushioning the return move.

ment of the arm to prevent injury to any part.

With the foregoing in view, the invention resides in the novel construction and asso ciation of parts hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawings.

Figure 1 is a side elevation partly in section showing my invention.

Figure 2 is a horizontal sectional view as indicated by line 22'ot Fig; 1.

In the drawings above briefly described, the numeral 1 designates a hollow standard adapted to rise from a garage floor, side Walk or other appropriate support, as illustrated in the application above referred to. The upper end of the standard 1 is provided with a cap or head 2 which is swivelled thereon and carries a circular upstanding frame 3 for holding a pair of lenses 4, said frame and lenses forming a globe adapted to contain an electric light 5 whereby the device may be illuminated at night and advertising matter or thelike displayed upon the lenses. The head 2 is provided below the frame 3 with an opening 6 and the inner end 7 of a tubular hose-carrying arm 8 extends through said opening and is pivotally Specification of Letters Patent.-

mounted on the head as shown at 9. The

tire inflation hose 10 leads from a. suitable source of pressure and extends upw-(irdly through the standard 1 and the arm 8, the

' armwill swing downwardly and permit easy application of the hose to thetires to be inflated. I have shown avertical rod 11 in v standard 1, connected wfith"the inner end i of the arm theflo'wei end of said rod b'e- 1115; connected with a coiled springer the like 12 which is secured in the standariil 1 and serves to return the arm to raised position after it hasbeen lowered for use. a

To absorb the shock when the arm 8 is returned to a raised position, I rigidly mount a- .dash-pot cylinder 13 in the frame 3 as seen more clearly in Figure 1, the piston rod 14 of the dash-pot being connected in any preferred manner tothe upper end of a. rod 15 whose lower end is pivoted to the inner end 7 of the arm 8. The internal construction of the dashpot is such as to permit the arm 8 to swing downwardly without any appreciable resistance, but when this arm is released and the spring'lQ acts on the arm to return the same to vertical position, the. piston 16 of the dash-pot is checked in its descent, with the result that the shock is absorbed and no injury occurs to any part.

lVhile any suitable means inay be em ployed for mounting the cylinder 13, I prefer to provide the lower end of said cylinder with a threaded stud 17 which is threaded in an opening 18 in the bottom of the frame 3, this portion of the bottom being in the form of a lug 19 extending into the opening 20 through which the rod 15 and the carrying conduit of the light 5 extends.

I prefer to employ a water-supply hose 21 leading from a water pipe 22 within the standard 1, so that the radiators of automobiles may be filled conveniently at the time of inflating the tires.

From the foregoing, it will be seen that I have provided a unique arrangement of parts for carrying out the object of the invention and since excellent results may be obtained from the details disclosed, they are referably followed. It is to be understoo however, that Within the scope of the invention as claimed, numerous minor changes may be a made.

I claim: I l. A tire inflating device comprising a hollow standard, a head swivelled on the upper end of said standard and carrying a globe, one side of'said head having an opening, a hose-carrying arm extending into the head through saidopening and pivoted to the head, means for normally raising said arm, and. means confined in said globe and connected with the inner end of saidarm, for

' cushioning the return movement of the latter to vertical position.

2. A tire inflating device comprising a standard, a head swivelled on the upper end of. said standard and carrying a globe communicating With the interior of the standard, the side of said head having an opening, a

hose-carrying arm pivotally mounted in said opening and extending into the interior of the head, counter-balancingimeans for. said arm locatedin said standard and connected to the inner end of said arm, a rod rising .r

from said inner end of the arm into said globe and a shock-absorbing device mounted a in said globe and connected 'with the upper end of said rod. 7 V V 3.-A tire inflating (lQVlCB comprising a standard, a head s vivelled on the upper end of said standard and carrying a globe communicating With the interior of the standard,-

the side of said head having an opening, a hose-carrying arm pivotally mounted in said opening and extending into the interior of the head, counter-balancing means for said arm located in said standard and connected to the inner end of said arm, a rod rising from said inner end of said arm into said globe, a dash-pot'in said globe, the piston rod of said dash-pot being connected with the upperend of said rod, and athreaded stud on the cylinder'of said dash-pot, the

bottom of said globechaving an opening into which said stud is threaded.
